You could be experiencing a contact dermatitis from the
ZenMed product you are using for your acne. I would discontinue use and make an
appointment today for further evaluation and treatment. Advanced Dermatology
offers comprehensive treatment options for both medical and cosmetic treatment
Irritant Dermatitis from acne treatment
It looks and sounds like you gave yourself an irritant dermatitis from that acne treatment product. I would stop that product if you haven't already, and apply an over-the-counter hydrocorticosone 1-2% with aloe ( from the pharmacy), 2x/day. That should calm it the fastest without causing more problems. Then see a dermatologist for better management of your acne. I would not take antibiotics.
